You will require the following components with
your new Direct Vent Freestanding Gas Stove.
Please review your product to make sure you
have everything you need. In the event that you
are missing any part, contact your dealer.
Note: These are the minimum pieces
required. Other parts may be re-
quired for your particular installa-
tion. See above for a list of vent
parts.
If installing termination on a siding covered wall,
a vinyl siding standoff or furring strips can be
used in order to ensure that the termination is
not recessed into siding.
The vinyl siding standoff is required for walls
with vinyl siding.

A) Dura-Vent Horizontal Termination Kit
B) Wall Thimble (required for combustible
walls)
Minimum components for a Dura-Vent

HORIZONTAL
INSTALLATIONS
1)
Set the unit in its desired location. Check to
determine if wall studs are in the way when
the venting system is attached. If this is the
case, you may want to adjust the location
of the unit.
2)
Assemble the desired combination of pipe
and elbow to the appliance adapter with
pipe seams oriented down. Offset the pipe
seams as double seams in one place will
cause the outer pipe to take an oval shape.
Kit comes complete with 18" of straight vent
- 6-5/8" dia. black outer pipe and 4" dia. inner
vent.
3)
With the pipe attached to the stove, slide the
stove into its correct location, and mark the
wall for a 9-1/2" (inside dimensions) round
hole. The center of the round hole should
line up with the centerline of the horizontal
pipe, as shown in diagram 1. Cut and frame
the 9-1/2 round hole in the exterior wall
where the vent will be terminated. If the wall
being penetrated is constructed of non-
Note:
a)
The horizontal run of vent should have a
1/4 inch rise for every 1 foot of run towards
the termination. Never allow the vent to run
downward. This could cause high temper-
atures and may present the possibility of a
fire.
b)
The location of the horizontal vent termina-
tion on an exterior wall must meet all local
and national building codes, and must not be
blocked or obstructed. For External Vent
Terminal Locations, see diagram on page 9.
c) Snorkel Terminations:
For installations requiring a vertical rise on
the exterior of the building, 14-inch and 36-
inch tall Snorkel Terminations as shown in
Dia. 2 are available, as well as the standard
Riser Vent. Follow the same installation
procedures as used for standard Horizon-
tal Termination. NEVER install the snorkel
upside down.
